Big Bang Theory's Mayim Bialik and Kunal Nayyar rip into each other in epic rap battle

Mayim Bialik has showed off her rhyming skills while hurling insults at her Big Bang Theory co-star Kunal Nayyar during an appearance on Drop the Mic, a show in which celebrities face off in a comedic rap battle.

Nayyar (who plays Raj on the hit sitcom) kicked off the battle by slamming Bialik for being a child star, and leaving "TV for a PHd" in neuroscience, but Bialik came back with vengeance when she took aim at her costar's British-Indian heritage.
